ROOF-GARLINFI.

Specification of Letters Patent.

Application filed November is. 191:3. Serial No. scores.

a rarline is subjected.

The object of the invention is a carline for a freight car roof adapted to stiffen the roof against distortion from any or all ('itLlSQS.

The improved carline is clearly set forth in the following description and shown in the accompanying drawing, in which like numbers designate like parts, and

Figure 1 represents a plan view of the finished carline, assembled between the side plates of a car roof; Fig. 2 is a side elevation of the carline of Fig. 1, showing also the ridge pole and purlins in cross section; Fig. 3 represents an end elevation of one leg of the 'carline, showing the foot for securing it to the side plates; and Fig. 4: represents a transverse section through the center of a carline on the line 4't4 in Fig. 1, illustrating the manner of securing the channels together by top and bottom cover plates. This figure also shows the ridge pole of the car in cross section, and a ridge pole bolt. a

The carline 11 is made of two channel irons 12 connected by plates 13. Each carline thus formed is in plan X sha e with the diverging ends turned outwar ly, and adapted to be secured to the side plates 14;. Holes are suitably put in the upper flanges of the carline to secure Wooden members, as root purlins and the like. The cover plates 13 are riveted to the upper and lower flanges resist the manv diderent stresses to which of the channels and rigidly connect the bent sections at the center.

The ridge pole l5 and purlins 16 may be secured to the car-lines by bolts 17. The purlins form braces for the legs of the carlines to stiffen them against twisting.

The advantages of my invention are the utilization in the carline throughout of a full section ot metal in each member, without cutting away any portion of the original section, or altering or reducing its strength.

By connecting the two sections by cover plate at. the middle, forming a box girder at the ridge, a structure is produced of maximum strength and minimum weight. The

box section at the center will resist both Patented June 1914- the vertical and longitudinal strains, and especially the torsional strains produced freight car carlines.

Having described a particular embodimei'it of my invention, I do not limit myself thereto, but desire to secure by Letters Patent the following:

1. In a car roof, a built-up carline con-' sistingv of main half-length members extending from the side plates to the ridge and converging at their middles, and a middle connecting member secured to the middle of each of said half-length members and having a horizontal upper face adapted to support a ridge piece, both ends of each of said half-length members sloping downward toward the same side of the car and being secured to the side plate of the car.

2. A carline comprising two channel bar sections placed on edge and extending from the side of the car to near the ridge, and:

having portions bent to lie parallel to the ridge line, means for securing said parallel portions together consisting of a conneetin member rigidly secured thereto, and a sti ening plate secured to the lower flanges of said channel bars near the ridge.

3. A carline comprising two end members bent at the middle and each having its ends in the same plane and extending in the same general direction, the middle portions of said end members being secured together by means of top and bottom plates, and the end portions extending downwardly away from each other and having their extremities adapted to be secured to the side plates of a car.

4. In a car roof, a built-up carline consisting of V-shaped members placed with their points adjacent to each other, and a pair of cover plates secured thereto and inclosing the space between the points of said V-shaped members, the ends of said V- shaped members diverging toward the same side of the car and being secured to the side plate of the car.

5. A carline comprising a box girder middle portion and end portions diverging downwardly therefrom and adapted to be secured to the sideplates of a car.

6. A carline comprising a box girder middle portion and channel-5113112 end p0rcross-section and being arranged crosswise In tlons diverging downwardly therefrom and I of the (:arhne. adapted to be .scured to the aide. plates of Signed at St. Laws, Missouri, this 5th a car. day of 1\'ove mber, 1913.
